INHALER Filed Nov. 4, 1936 C] n uc nkyn J E. Flew Patented Mar. 2, 1937 UNIED STA ATNT ice 1 Claim.

This invention relates to inhaling devices generally; and more particularly to inhalers of the small tubular type adapted to be applied directly :to the mouth or nose of a person for the purpose of relieving nasal, throat and bronchial irritasection shown in Figure 2; and

Figure 4 is a development of the outer casing of the inhaler.

As shown in the drawing, the inhaler comprises a tube 5, preferably made of some sheet material 25 such as celluloid which will retain its tubular shape when rolled to such shape under the application of heat; The tube 5 is adapted to contain a roll of gauze 6 designed to be medicated by saturation with any desired liquid remedial agent.

* 30 The sheet from which the tube 5 is made is substantially rectangular in shape. Adjacent one of the corners, the sheet is provided with a slit 1 for the purpose of forming a tab 8 which may be bent out of the plane of the sheet after the forma- 35 tion of the tube and in the manner shown in Figure 2 of the drawing to engage one end of the inserted roll 6, in order to prevent accidental removal of the roll from its tube.

The end of the sheet opposite to the end pro- 40 vided with the slit 1 is compressed during the formation of the tube, to form a substantially flat portion forming a mouth piece 9 adapted to be inserted in the mouth of the user when the inhaler is to be operated through the mouth.

In forming the inhaler, a sheet of celluloid, cut to size, and provide withthe slit l, as shown in Figure 4, is rolled around a suitable forming tool 5 and is inserted in a brass tube of the desired diameter, flattened to form the mouth piece. The tube, with its inserted roll, is then immersed in boiling water and immediately removed and dipped into cold Water. The cooled tube retains 10 the shape imparted to it by this operation and is ready to receive the gauze roll which may be medicated as desired.

In order to retain the roll of gauze within the tube 5, the tab 8 is bent inwardly to form a stop for the said roll. The slot I should be of such length, and should be located from the adjacent edge of the sheet of celluloid as to cause the corners of the tab, when bent across the cylinder, to engage the inner surface of the tube frictionally. In other words, the tab 8 should be slightly less in width than the diameter of the tube 5, so that it will not form a plug capable of sealing the cylindrical end of the inhaler when it is bent into position for retaining the roll of gauze Within the tube 5.

It is to be understood that the invention is not to be considered as limited to the specific construction and arrangement described herein, since it is evident that many changes may be made without departing from the scope of the invention as defined by the claim appended hereto.

What I claim is:

An inhaler comprising a sheet of material rolled to form a substantially cylindrical casing, a filler of medicated material enclosed in said casing, said casing being flattened at one end to retain the filler within said casing, and a stop integral with said sheet and bent across the cylinder to prevent removal of the filler therefrom.
